Subject: radv/query: handle multiview timestamp queries.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=032014ac01a2dfd6c8e689b3d59989eb6fa2396b;p=mesa.git

radv/query: handle multiview timestamp queries.

For each view bit we need to emit a timestamp query.

Fixes: dEQP-VK.multiview.queries*
